Electrolysis using tungsten rods and KOH
« on: April 18, 2010, 23:25:23 pm »
I just tested performing electrolysis using 2 tungsten rods and koh mix.

reaction starts at about 1.2 volts

only the negative rod shows gas,

nothing at all on the positive rod, even when I raise the voltage to 8 volts.

why no gas (oxygen) on the positive rod?

Probably a chemical reaction which will form a coating , just like with the aluminium tube we tried last year?

I'm glad you mentioned that.. maybe this water i'm using was some leftover from last year's tests and is contaminated with ALU.

will test again with a clean mix.

yes there was some aluminum dissolved in the solution. that is why only hydrogen was being generated.
